The Senate on Tuesday blocked an amendment to pending transportation legislation that would have mandated a huge expansion of offshore oil-and-gas leasing, opened the Arctic National Wildlife Refuge to drilling and approved construction of the Keystone XL oil sands pipeline.

Sen. Pat Roberts’s (R-Kan.) amendment, which failed 41-57, would have also extended several energy efficiency and renewable fuels tax incentives and extend a pay freeze for federal workers, among other provisions.
